Provided is a device for transmitting wireless power. The wireless power transmitting device includes a communication unit, a power receiving unit, and a processor. The processor is configured to obtain, through the communication unit, communication establishment information and location information associated with a wireless charging area from a tag device, establish, through the communication unit, communication with a wireless power transmitting device based on the communication establishment information, and control to transmit the location information to the wireless power transmitting device. The power receiving unit wirelessly receives the power from the wireless power transmitting device after the communication unit transmits the location information.

A system and method for a context-aware digital assets distribution platform. The platform comprises means for distributing or broadcasting digital assets to mobile devices in conjunction with an object providing dynamic sources of context information. The digital assets distribution platform incorporates one or more component architecture, a mobile device application having one or modules for dynamic context sensing, context recognition, context and information communication-transmission, and digital assets content sharing via a mobile computing network. The platform enables the distribution or broadcast of personalized information or services to mobile device users.

A charging service method includes transmitting information of a communication device to a charging station, transmitting information of the charging station to the communication device, acquiring available service information of the charging station from a charging station server according to the information of the charging station, selecting at least one service option for generating charging service information, transmitting the charging service information to the charging station server, generating charging station certification information to the communication device, relaying the charging station certification information from the communication device to the charging station, and enabling a charging function of the charging station to charge the communication device after the charging station certification information is received by the charging station.

Two-way exchange vending can be performed by a two-way exchange based vending machine. The two-way exchange based vending machine can vend rechargeable batteries. The two-way exchange based vending machine can include different modules to perform different functionalities. The two-way exchange based vending machine can include a communications module, a dispensing module, a rejection module, and a receiving module. The communications module can communicate information to and receive inputs from a user. The dispensing module can dispense one or more rechargeable batteries or other requested products to a user. The receiving module can receive one or more rechargeable batteries from a user.

A charging system is configured to charge a charging target group including electronic devices which are stacked in a row and include their respective secondary batteries. A first receiver is configured to acquire, from the electronic devices, pieces of battery information representing remaining capacities of the secondary batteries, respectively. The second receiver is configured to obtain, from the electronic devices, pieces of position information representing positions of the electronic devices in the charging target group, respectively. The determining processor is configured to determine respective priorities of the electronic devices according to the pieces of battery information and the pieces of position information based on a judgment condition. The charge controller is configured to control charging of each of the electronic devices so that the electronic devices are charged according to the respective priorities.

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To avoid theft and tampering of the portable electrical energy storage devices, by default, each portable electrical energy storage device is locked in and operably connected to the vehicle to which it provides power unless the vehicle comes within the vicinity of a collection, charging and distribution machine or other authorized external device such as that in a service center. Once within the vicinity of a collection, charging and distribution machine or other authorized external device a locking mechanism in the vehicle or within the portable electrical energy storage device unlocks and allows the portable electrical energy storage device to be exchanged or serviced.

Methods and systems for transaction utilizing electronic device battery monitoring are disclosed herein. An electronic device may include a battery with a power level sensor. The power level may be monitored and, if the power level is below a threshold level, power draw of the electronic device may be reduced by shutting off one or more non-essential or low priority applications. Other transaction saving techniques may also be disclosed such as communicating data to the transaction server to allow for the transaction to be easily continued and/or indicating that the transaction should be automatically processed.

According to an embodiment a wireless power transmitting device, includes a power transmission antenna including patch antennas to wirelessly transmit power, and communication antennas configured to receive a communication signal from an electronic device. The wireless power transmitting device also includes a processor configured to detect a direction in which the electronic device is positioned based on the communication signal received through the communication antennas and control the power transmission antenna to transmit the power in the detected direction.

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices. To charge, the machines employ electrical current from an external source. As demand at individual collection, charging and distribution machines increases or decreases relative to other collection, charging and distribution machines, a distribution management system initiates redistribution of portable electrical energy storage devices from one collection, charging and distribution machine to another collection, charging and distribution machine in an expeditious manner. Also, redeemable incentives are offered to users to return or exchange their portable electrical energy storage devices at selected collection, charging and distribution machines within the network to effect the redistribution.
